    Usage

    RNZebraBluetoothPrinter

    RNZebraBluetoothPrinter is a module for Bluetooth management and supports print functionality for zebra bluetooth printers ( only ble devices ). It includes features like bluetooth enable/disable, pair/unpair a BLE/Bluetooth device, scan for nearby bluetooth devices and printing using bluetooth.

    import RNZebraBluetoothPrinter from 'react-native-zebra-bluetooth-printer';
     
    1. isEnabledBluetooth == > async function, check the status of bluetooth service in the bluetooth client(mobile phone) .Returns true if already enabled, false if not enabled.
    RNZebraBluetoothPrinter.isEnabledBluetooth().then((res) => {
        //do something with res
    })
    1. enableBluetooth == > async function, Android: requests for bluetooth on/off permission on the android device. iOS: resolves to nil.
    RNZebraBluetoothPrinter.enableBluetooth().then((res) => {
        //do something with res
    })
    1. disableBluetooth == > async function, Android: disables bluetooth if bluetooth is switched on. iOS: simply resolves by nil.
    RNZebraBluetoothPrinter.disableBluetooth().then((res) => {
        //do something with res
    })
    1. scanDevices == > async function, scans for available nearby bluetooth devices for a specific period of time.
    RNZebraBluetoothPrinter.scanDevices().then((deviceArray) => {
        //do something with res
    })
    1. pairedDevices == > async function, Android: returns already paired devices. iOS: resolves to nil.
    RNZebraBluetoothPrinter.pairedDevices().then((deviceArray) => {
        //do something with deviceArray
    })
    1. connectDevice == > async function, for both android and iOS
    RNZebraBluetoothPrinter.connectDevice(deviceAddress).then((res) => {
        //do something with res
        //for android, device address is mac address
        //for iOS, device address is a long string like 0C347F9F-2881-9CCB-43B0-205976944626
    })
    1. unpairDevice == > async function, Android: unpair/disconnect a paired device from paired device list.
    RNZebraBluetoothPrinter.unpairDevice(deviceAddress).then((res) => {
        //do something with res
    })
    iOS: function resolves to nil.		
    
    1. print == > async function, prints specific zpl string from a zebra printer for both android and iOS. For example :
    const zpl = "^XA^FX Top section with company logo, name and address.^CF0,60^FO50,50^GB100,100,100^FS^ FO75,75 ^ FR ^ GB100, 100, 100 ^ FS^ FO88, 88 ^ GB50, 50, 50 ^ FS ^XZ";
     

    Android

    RNZebraBluetoothPrinter.print(deviceAddress,zpl).then((res) => {
        //do something with res
    })

    iOS

    RNZebraBluetoothPrinter.print(zpl).then((res)=>{
        //do something with res
    })
